This postscript about DCC applies to Lenz only.
1. The Lenz LE080XS decoder with a motor current rating of 700 ma has proven
to be adequate (with margin) among the NWNG crowd for locos up to PBL K27s.
I've not heard of nor experienced any decoder failures due to stall current
exceeding this rating.
2. The Lenz systems have some anomalies having to do with two digit versus
four digit addressing. Jim Brown has demonstrated that all is well if two
digit address are used exclusively. I have demonstrated that all is well if
four digit addresses are used exclusively.
3. I have demonstrated that my Lenz system has problems when MIXING BOTH two
digit and four digit addresses. That;s why Goose #5 has an address of 10,
which the Lenz treats as a four digit address.
4. There are a couple undocumented CVs in the Lenz system. One allows you to
read out the version number of the PLCC (Programmable Logic Controller Chip)
in the hand held throttle. The PLCC is the "computer" in the throttle, and
the only changes from version to version are in the PLCC software. It is a
field programmable device, but the only practical way to upgrade is by
swapping chips with Lenz.
When I get back home in about ten days, I can look at my documentation for
the address of the version CV. Also, I don't remember if the "reset" CV is
documented or not, or if there any other undocumented ones. I do, however,
know that the Lenz documentation is fuzzy on some items. For example, Set 02
allows five hand held throttle addresses: 1,2,3,29, & 30. (The default is 2)
Yet the documentation says set 02 supports SIX hand helds. Does this mean
that the address of the handheld acting as command station does not matter,
or that only five are actually supported? I can't answer this because I
don't have six throttles for a test.
I hope my two diatribes have demonstrated that:
1. DCC is not for the faint of heart.
2. Lenz documentation stinks.
However, I love DCC and have no plans to ever switch back.
